Peter Klausler 8f01ecaeb8 [flang] Special-case handling of INTRINSIC in type-decl-stmt (#86518) ...

Fortran allows the INTRINSIC attribute to be specified with a distinct
attribute statement, and also as part of the attribute list of a
type-declaration-stmt. This is an odd case (especially as the declared
type is mandated to be ignored if it doesn't match the type of the
intrinsic function) that can lead to odd error messages and crashes,
since the rest of name resolution expects that intrinsics with explicit
declarations will have been declared with INTRINSIC attribute
statements. Resolve by handling an "inline" INTRINSIC attribute as a
special case while processing a type-declaration-stmt, so that

  real, intrinsic :: acos, asin, atan

is processed exactly as if it had been

  intrinsic acos, asin, atan; real acos, asin, atan
